Abstract

The purpose of this study was to clarify the effect of changing footwear conditions on postural response against postural perturbation. Twenty-three healthy subjects participated in this study. Postural response was induced by moving a platform forward, hereafter referred to as forward-perturbation of a platform. The center of pressure (COP) from the force plate and the electromyograms (EMG) of the tibialis anterior (TA) and quadriceps femoris (QUAD), which are both agonists of the response, were measured. The effect of plantar material and shape of footwear on postural response was examined as footwear condition. Changing plantar materials had an effect on integrated EMG of the agonists (IEMG) but not on the response pattern. On the other hand, the shape of footwear had an effect on the response pattern but not on IEMG. It was supposed from this result that changes in somatosensory input, caused by coupling of plantar material and shape of footwear, modifies postural response variously.

摘要

本研究的目的是阐明改变鞋类条件对姿势扰动时姿势反应的影响。23名健康受试者参与了本研究。通过向前移动平台诱发姿势反应，以下简称平台向前扰动。测量了来自测力板的压力中心（COP）以及反应的两个主动肌即胫骨前肌（TA）和股四头肌（QUAD）的肌电图（EMG）。作为鞋类条件，研究了鞋底材料和鞋类形状对姿势反应的影响。改变鞋底材料对主动肌的积分肌电图（IEMG）有影响，但对反应模式没有影响。另一方面，鞋类形状对反应模式有影响，但对IEMG没有影响。从这一结果推测，由鞋底材料和鞋类形状的耦合引起的体感输入变化会以多种方式改变姿势反应。
